错误“SIP/2.0 488 此处不可接受”

【问题标题】：Error "SIP/2.0 488 Not acceptable here"错误“SIP/2.0 488 此处不可接受”
【发布时间】：2015-12-14 21:40:12
【问题描述】：

我设置了用户“100”和“200”，我正在尝试使用项目 sipml5。

服务器记录了这两个在线电话上的用户“100”。

用户“200”记录在 sipml5 中，但要调用它会显示此错误：

【问题讨论】：

  • 离题。不是编程问题。我们不是一般的服务器/软件技术支持。

标签： asterisk sip


【解决方案1】：

488应该意味着没有媒体兼容性。

获得 488 有几个原因：最常见的是您没有通用的编解码器。首先检查您的星号上是否支持和配置了作品。

由于 webrtc 兼容性，问题通常与以下用途有关：

UDP/TLS/RTP/SAVPF

而不是

RTP/SAVPF

ie：webrtc/ietf 标准尚未完全定义，仍在发展中。

您可以在此处查看可能重复的问题/答案：Freeswitch and webRTC: media rejected with 488

【讨论】：

  • 那么安装 Opus 有帮助吗？我也有同样的情况，我已经安装了 Opus。
【解决方案2】：

当我使用 SRTP 接听电话时，我遇到了这个问题。电话通过带有 488 的电话掉线。我可以毫无问题地拨打加密电话。
